The connection between the pipes is made tighter by the arrangement of the first rubber pad 3 and the second rubber pad 7.

[0029] Specifically, the inner polyethylene layer 10 is fixedly connected to the inner wear-resistant rubber layer 9. The arrangement of the inner wear-resistant rubber layer 9 enhances the internal service strength of the pipe body 1 and reduces the damage of the pipe body 1 by minerals.
